Curvilinear perspective, also five-point perspective, is a graphical projection used to draw 3D objects on 2D surfaces, for which (straight) lines on the 3D object are projected to curves on the 2D surface that are typically not straight (hence the qualifier "curvilinear"[citation needed]). It was formally codified in 1968 by the artists and art historians André Barre and Albert Flocon in the book La Perspective curviligne,[1] which was translated into English in 1987 as Curvilinear Perspective: From Visual Space to the Constructed Image and published by the University of California Press.[2]
Curvilinear perspective is sometimes colloquially called fisheye perspective, by analogy to a fisheye lens. In computer animation and motion graphics, it may also be called tiny planet.
